Move pbx to new location/subnet - receipe what has to be done?

[nobody]

A customer moves a subsidiary of his company which has its own 3cx pbx to a new physical location. The pbx currently running on Hyper-v as a vm should also be moved. Still, the VM will be part of the active directory domain connected via VPN, users will be remain the same, phone numbers, phone-provider, Exchange server.
The only thing (to my knowledge) which will be changed is the subnet. I later might change the public name of the pbx from a 3CX maintained FQDN to a customer specific.
I already have setup a replication of the vm to the new location. When the move is complete, I plan to do a failover to the new location.
Then change the internal and external address, reprovision the phones. Done.
My question: Will this procedure work, or should I better uninstall and reinstall the pbx?

I've dabbled a little in this area.
It seems 3CX doesn't mind if there are changes like that, so long as you adjust the values in the admin UI.

Sounds good. Thank you for your answer!

Make sure you have a full backup of the system before you make any changes so you can easily revert if something goes wrong.
Other than that the PBX will detect the change of the local IP and will prompt you to change it. The public IP will automatically updated if the PBX is set to Dynamic.
For future reference changing the FQDN of the system requires uninstalling and reinstalling. You will also need to release the licence key from the FQDN through the costumer portal.
